There’s More to Red Than Roses: 10 Outstanding Red Flowers for the Garden

As Valentine’s Day approaches and we are surrounded by endless bouquets of monotonous red roses, I long for the beautiful red flowers that grace my garden throughout the year. Red has always been my favorite color, and I was quick to incorporate it into my garden. One of my first flower beds was a “hot colors” garden that I could see from my kitchen windows – a large kidney-shaped island of fiery red, orange, and gold perennials set against a background of my neighbor’s lush green arborvitae hedge. These sunset colors define “summer” for me, and I use the perennials in endless bouquets for my home.

As time went by, my passion for red outgrew the perennial bed, and found its way into a shrub border that complements this part of my garden. Red rhododendrons, red-leaved Japanese maples and crabapples, and the bright red berries of winterberry carry on the theme. I now have red in my garden through most of the year.

When using red in the garden, keep in mind that there are “warm” reds with a touch of yellow that combine well with oranges and yellows, and “cool” reds with a touch of blue that are better with blues and purples. Silver-leaved foliage is a perfect foil for both shades, and softens the brightness of the blooms.

Here are ten outstanding red flowers for your garden:

Tulip Darwin Hybrid ‘Red Impression’

This classic red tulip never disappoints! Unlike other tulips, the Darwin Hybrids have exceptional perennial qualities, and mine have bloomed for at least 10 years! A mid- spring bloomer, 22” high with large, bright red flowers atop sturdy stems.

Rhododendron ‘Henry’s Red’

This rhododendron has the deepest ruby-red trusses that I have ever seen. With funnel-shaped flowers that have a dark red throat, it is a stunning sight in the May garden. Henry’s Red is a Mezitt hybrid, prefers full sun to part shade and grows to about 5’ tall.

Azalea ‘Hino Crimson’

A dwarf, low growing, compact shrub with brilliant red flowers in mid May, this azalea is one of the most popular and reliable evergreen azaleas in New England. As a bonus, its foliage turns a handsome dark red in autumn.

Bleeding Heart: Dicentra spectabilis ‘Valentine’

With deep red flowers gracefully suspended along arching burgundy stems, Valentine is a sophisticated new variety of a beloved garden classic. Plants are vigorous, with plum-colored new growth and bronzy, gray-green foliage. They make a handsome show in large containers.

Daylily: Hemerocallis ‘Lusty Lealand’

Lusty Lealand sports huge (6.25”) flowers on tall sturdy stems. The deep red flowers have yellow throats and last for several weeks in July.

Bee Balm – Monarda “Cambridge Scarlet’

Bee Balm sports brilliant red frilly starburst heads atop strong upright stems. The tubular florets are very attractive to bees, butterflies and hummingbirds. A hardy plant that blooms in mid summer, 4-5’ tall.  

Begonia ‘Dragon Wing Red’

This begonia, with its angelwing-like, shiny green leaves and large drooping scarlet flowers, is my favorite annual for shady containers. It is a compact, bushy, fibrous-rooted plant, 15-18” tall, with fleshy, semi-trailing stems, and flowers that bloom until first frost. I have good success overwintering these begonias in my house.

Canna ‘The President’

 ‘The President’ Canna is known for its extremely vibrant, large red blooms, and lush, green leaves that are edged with a fine line of burgundy. Cannas add a tropical look to the garden, are perfect for containers, and prefer moist garden soil and full sun.

Cardinal Flower: Lobelia Cardinalis

This native clump-forming perennial features erect spikes (racemes) of large, cardinal red flowers on stalks rising to a height of 2-4 feet. It blooms in August to September, and its tubular flowers are very attractive to butterflies and hummingbirds. Since it grows naturally in along streams and springs, it is a perfect plant for a Rain Garden or moist location.

Dahlia ‘Bishop of Llandaff’

This classic dahlia cultivar is enjoying a resurgence of popularity, and no wonder! Its semi-double scarlet blooms are carried above foliage so dark it's almost black. Bishop of Llandaff grows to 36” in height, and blooms July-October.

Blue Star Glitters in the Winter Landscape

inter is the season when conifers really come into their own in the garden. They provide much needed structure, form, texture and color at a time when the landscape can look so bleak. One of my favorite conifers for year-round interest is the “Blue Star” juniper, a slow-growing dwarf evergreen shrub with an intense silver-blue hue.

When you mention junipers to a gardener, the name often conjures up images of a sea of boring groundcover in the mall parking lot. A self-described “plantaholic” friend of mine was recently looking for plants for a large sunny slope that she had just cleared. She needed plants that would hold the soil, tolerate sun without supplemental watering, and require minimal pampering on this steep terrain. When I suggested the Blue Star juniper, she looked at me with disbelief. What does a juniper have to offer the experienced plant collector?

Junipers are not all the same, however, and as with other plant species, there are many new cultivars available to the home gardener. I have come to love “Blue Star” juniper in my own garden because its intense blue color complements so many plants. For a striking color contrast of opposites on the color wheel, you can plant this juniper with gold threadleaf cypress or other gold colored plants.

In my own garden, I use ‘Blue Star’ in the sunny beds around my home, where a color palette of blues, silvers, purples and pinks complements my blue-gray house. Blue Star looks fabulous with deep pink azaleas and Geranium sanguineum, alongside the variegated Euonymous ‘Gaiety’ and fuzzy Lambs Ears, at the base of my bright blue ‘Endless Summer’ hydrangeas and intereplanted with Heuchera ‘Silver Scrolls’ in an area of partial shade. The key is in the plant “marriages”, and Blue Star is the perfect companion for so many perennials and shrubs!

Blue Star juniper (Juniperus squamata ‘Blue Star’) is slow-growing and has a low, mounded habit. It grows only to about 1 foot tall in five years, but will eventually mature to 2-3’ high. Its dense, awl-shaped foliage provides an interesting texture in the garden. The upper silver-blue surfaces of the leaves add brilliant color and a star-like sparkle. It is commonly called “singleseed juniper” because each bluish, berry-like, female cone contains but a single seed. Like other junipers, it is cold-hardy, thrives in full sun to part shade, and requires good drainage. Once established, this shrub tolerates droughts, and dry, shallow rocky soil. Horticulturalist and conifer collector Adrian Bloom calls Blue Star “arguably the best dwarf conifer ever raised.”

Blue Star’s dwarf size and neat appearance make it an ideal shrub for foundation plantings and small gardens. It is perfect for the front of a shrub border, in rock gardens, or showcased as a focal point plant to be admired for its color and shape. It also provides erosion control on slopes. It's a no-maintenance evergreen ground cover for sunny areas and a well-behaved companion that will not invade and overpower its neighbors. And for those of us in northern climates, Blue Star provides beautiful foliage that glitters in the winter garden.

Nine New Perennials for Your Spring 2014 Garden

January is a great time to peruse plant catalogs and choose some new perennials to bring pizzazz to the spring garden. After a long winter, I am outside every day in early spring, watching the rapid changes in the garden as the perennials start poking out of the ground. And every year I wish that I had more plants for this delightful season!

Here are ten intriguing plants to add to our Zone 5-6 gardens this year:

From White Flower Farm

(whiteflowerfarm.com)

Pulmonaria ‘Silver Bouquet’

A silver-leaved Lungwort that shines in shade, this new pulmonaria is mildew resistant with lance-shaped silver foliage and flowers that change from pink to blue.

Blooms in April-May, height 7”, full or part shade, deer resistant

Polygonatum odoratum ‘Double Stuff’

Just what you need to brighten up a shady spot! This variegated Solomon’s Seal has foliage with very broad white margins, and fragrant white blooms in early spring.

Blooms in May, height 18”, full or part shade

Helleborus Winter Thriller ‘Ballerina Ruffles’

A hellebore with fluffy 2-3” double-petaled blossoms in gorgeous shades of pink with purple speckles. This vigorous cultivar features exceptionally large, outfacing flowers and thick, sturdy stems.

Blooms in March, height 18”, full or part shade

From Bluestone Perennials

(bluestoneperennials.com)

Heuchera ‘Paprika’

Heucheras, also known as Coral Bells, retain their brightly colored leaves throughout the winter, so they are wonderful plants for the spring garden. This variety has spicy, hot paprika colored foliage with silver veining that will add bold flair to your garden. White flowers hover above the blazing leaves.

Foliage color all year, blooms in early summer, height 8”, full sun to part shade

Helleborus Winter Jewels Amethyst Gem

A hellebore with amethyst-rose double flowers margined in opal. The finely sculpted blossoms brave cooler temperatures to become one of the first gifts of spring.

Blooms in March, height 12”, full or part shade

From Plant Delights Nursery

(plantdelights.com)

Glanthus nivalis ‘Flore Pleno’

There are more than 70 varieties of snowdrops in cultivation, but only a few are sold in the US. This award-winning snowdrop has a dangling white bell composed of several floral layers, each green edged in white. A delightful addition to the early spring garden!

Bloom in early March, height 6”, sun to part shade

From Arrowhead Alpines

(arrowheadalpines.com):

Beesia deltophylla

I saw this plant for the first time on a garden tour in Boylston in July and was really impressed! Another specimen brought to the US by Dan Hinkley from Sichuan, China, this is a beautiful groundcover for the woodland garden. Glossy, heart-shaped purple-tinged evergreen leaves form dense rosettes, and are topped with spires of white flowers.

Blooms mid to late spring, height 18”, full to part shade

Lathyrus vernus

Lathyrus is a non-climbing, clump-forming perennial sweet  pea with showy pink flowers and light green leaves. A low-maintenance plant that dazzles in the shady border!

Blooms in April, height 12”, full to part shade

Primroses

Arrowhead Alpines features a stunning 57 varieties of primulas (primroses). These are not the primroses that you find in the grocery store and that rarely return year after year. Primroses are a huge, diverse genus with flowers in every color of the rainbow. Although some species prefer cool, moist conditions, there are quite a few that can take the heat and dryness of the summer. It is worth browsing through this large collection of varieties and choosing a few to try in your own garden this spring.

I hope this list inspires you to add a few new varieties to your spring garden!

October Pleasures in the Garden

October is a month filled with fall garden chores - from cutting back dying perennials, to planting bulbs and the last new acquisitions still in pots, to preparing the houseplants for their return back into the house. It's easy to get caught up in the activity and not notice all the fleeting beauty that this month offers. Beautiful blooms, rich foliage and dramatic seed heads abound. In a few weeks it will all be gone, so take some time to enjoy the warm October afternoons outdoors in your glorious fall garden!

Chanticleer's Fabulous Fall Containers

I discovered Chanticleer Gardens last spring, and now that my daughter attends school nearby, I plan to visit this fabulous garden as often as I can. Last weekend I was once again inspired by the dozens of fabulous containers found throughout the garden. Each pot is a spectacular blend of foliage, color and texture, and most do not use flowers at all!

Many of these beautiful arrangements are made of tender tropicals - or houseplants for those of us in the Northeast. Now that I will be moving all of my houseplants back inside for the winter, I am thinking about creating a few Chanticleer-like pots to decorate the inside of my house!

A grouping of containers surrounds a cozy seating nook tucked in at the side of the house.

Last but not least, a chain of small succulent pots adorns a rustic column.

Creating a Jewelbox Entry Garden

Entry gardens are a challenge to design because they need to be interesting in all seasons. But they also provide a wonderful opportunity to showcase tiny interesting specimens that would be lost in a distant landscape.

We were delighted when our friend Deborah asked for assistance in designing a new entry garden for her suburban home. In addition to new foundation plantings, Deborah needed help with a small entry garden bed that is the focal point of her front yard.

The entry bed is a highly visible triangle bordered by the driveway, the walkway to the front door, and a winding brick path that Deborah installed herself. Mounded in the center, it has good drainage and dappled sunlight for most of the day. Deborah likes Asian-inspired gardens, and wanted to incorporate her ‘Crimson Queen’ Japanese maple, creeping phlox, hostas, and an unusual collection of geodes inherited from her grandfather.

Above, Deborah’s previous garden had included mostly sun-loving perennials that bloomed briefly and then blended into a mass of green. We wanted to give her garden interest throughout the seasons with fabulous colored foliage, different textures and a variety of plant forms.

Because the garden is so highly visible at close range, we came up with the concept of creating a “jewelbox” entry garden – a collection of small specimen plants with intricate details that delight the eye upon close inspection.

We decided to incorporate plants that would evoke an Asian garden. We chose a color scheme of yellows and maroons to complement Deborah’s house colors. And we came up with the concept of a large tufa trough that would serve as a focal point for the bed and unite several groupings of geologic specimens.

Hypertufa troughs look like stone, but are actually made of peat moss, perlite and Portland cement, so they are much lighter than they appear. Ours is filled with hens and chicks, mini hostas and a miniature carex.

Small objects in a garden, like these geodes, are more effective when grouped.

Although newly planted, the new garden already has interest from the variety of forms.

Our plant palette consists of spiky plants such as daylilies, dwarf iris, and blue fescue; low creeping plants such as sedum ‘Angelina’, creeping wooly thyme and Irish moss; large-leaved plants such as hostas and coral bells; and feathery plants such as Japanese painted fern and miniature conifers. As the plants mature, they will create a complex tapestry of colors and shapes.

Shades of maroon from the Japanese maple, red fountain grass, heuchera ‘Stormy Seas’ and the winter color of bergenia complement the home's brick façade and maroon shutters and doors.

Glimmers of gold from hosta ‘Great Expectations’, hanoke ‘All Gold’, heucherella ‘Sunspot’, yellow dwarf iris, and ‘Happy Returns’ daylilies echo the creamy yellow siding.

Four season interest will begin with miniature conifers and hellebores in winter; snowdrops, mini daffodils, creeping phlox, epimediums and bergenia in spring; alliums, irises, Astilbe ‘Key West’ and daylilies in summer; and hanoke grass, blue fescue, black mondo grass and ground-hugging sedums in fall.

Unusual miniatures include alpine lady’s mantle, carex ‘Beatlemania, and mini hostas ‘Stilleto’. 'Kii Hime', 'GinkoCraig', ‘Lakeside Cha Cha Downsized’ and 'Lakeside Baby Face'.

​The jewelbox garden is grounded by a simple foundation planting of ‘Green Lustre’ hollies, hydrangea ‘Quickfire’ astilbes and epimediums, along with a hosta hedge that was already on the property.

Shady Partners

Garden tours provide a wonderful opportunity to view private gardens, discover new plants, and meet the garden owners that have created these beautiful retreats. Sometimes the most interesting gardens are the smallest, such as this Sterling garden that I toured on the Garden Conservancy's Worcester, MA Open Day in late July.

The owner, who had served as a docent at Tower Hill Botanic Garden, had accumulated an intriguing collection of plants for her mostly shaded garden. My friend Julie and I were stumped by some of these rare beauties, and had to research them once we got home and add them to our own wish lists.

The real success of the plantings came from her artistic eye, as she grouped these shade plants for wonderful effect. Here are a few glimpses of her shady paradise:

n unfailing trio for the shade: any combination of heucheras, hostas and ferns. The plants in this garden were incredibly robust thanks to the owner's annual application of a thick layer of home-made leaf mulch.

A trio of young Paw Paw trees intrigued me as I had just received a pair of Paw Paw sapplings last summer. Paw Paws are native to North America and produce a large fleshy fruit with a flavor similar to mangoes and bananas.

Hydrangea Heaven

I love the lush flowers of hydrangeas both in the garden and in bouquets for the house. As a novice gardener, I had mixed success with growing hydrangeas and getting them to bloom every year. There are dozens of tantalizing hydrangea varieties, and the key was finding the best ones for my mid-Massachusetts location.

Planting several types of hydrangeas ensures color in your garden from June through October. Here are the hydrangeas that are blooming in my garden right now:

Hydrangea 'Annabelle' has been in bloom since late June. This hedge is five years old, and has provided me with more than 20 new plants. Annabelles are very easy to propagate via layering.

Annabelle's flowers fade from pure white to a soft chartreuse.

Hydrangea 'Endless Summer' is the most reliable blue mophead for my area because it blooms on both old and new wood. It is lovely paired with blue hosta and blue shrubs such as Juniper 'Blue Star' above.

Hydrangea 'Pinky Winky' has loose panicles of flowers and is blooming well in the shade of two dogwood trees.

Pinky Winky's rosy flowers are highlighted by the pinkish new growth on Leucothoe 'Girard's Rainbow'.

Hydrangea 'Glowing Embers' is a new addition to my garden. I could not resist the deep pink and chartreause color combination of the flowers.

Hydrangea 'Fuji Waterfall' has white double florets tinged with pale blue and thick, shiny green foliage.

Hydrangea 'Wedding Gown' also has pure white double flowers that fade to a deep red in autumn.

Hydrangea 'Pink Diamond', in its second year in my garden, is a robust grower. Its flowers open in white and fade to a dark rose color by fall.

Hydrangea 'Little Lamb" was a rescue plant from Lowe's 50% off bin last year. It's growing well in a pot on the patio, and sports flowers that are similar to a PeeGee but much smaller.

Hydrangea 'Limelight' is just starting to open its buds. The flowers on this strong shrub will be close to 18" in diameter when they are fully open. They are a glorious contribution to the fall garden.

July is Perfect for Dividing Bearded Iris

Bearded irises are relatively easy garden plants to grow, and will give good results with a minimum of care. My collection of irises came about through the generosity of a fellow gardener – an elderly gentleman from the Historical Society. We met at a Society function during my first spring in town, and found that we shared a common hobby. On a sultry, hot day in mid-summer, he dropped by with several trash bags filled with iris rhizomes. His mother had been an Iris Society member and avid collector, so the irises that he inherited and then shared with me were heirloom plants and unusual varieties. Twenty years later, their dazzling pale pink, frosty blue and midnight purple blooms light up my garden in late spring.

Here in Massachusetts, July and August are the best months of the year to plant new iris rhizomes and divide overcrowded clumps. The irises have finished flowering, and are usually dormant during the heat of the peak summer months. Iris rhizomes that are planted now have plenty of time to have their roots well established before the end of the growing season.

Bearded iris should be divided when they become overcrowded, usually after three to five years. At this point, their bloom will decline. Dividing them is not difficult, since the plants have fairly shallow root systems. I follow these steps:

1.     To divide a mature clump, carefully lift the entire plant out of the ground. I like to use a spading fork for this job, as it does not cut the roots.

2.     Next, rinse the soil off the rhizomes so that you can see any diseased areas.

3.     Separate old, exhausted, unproductive rhizomes from new, young growth.

4.     Cut off any portions that are brown inside and discard.

5.     Slice the healthy portions into chunks about 3” in length. Make sure each piece has its own roots and leaves.

6.     Prepare a planting site in full sun where the soil has excellent drainage – raised beds and slopes are ideal for this. Amend the soil with compost.

7.     Space the plants 12-24 inches apart. Clumps of three plants set in a triangle with the rhizomes facing into the center makes an attractive grouping.

8.     Lay each rhizome horizontally in its own shallow hollow. It needs to be half-buried so that the back of each rhizome is visible (like a floating whale). Tamp the roots firmly into the ground to anchor the rhizome.

9.     Trim the leaves to about 6”. This will reduce transpiration while the plant is becoming established.

10.     Keep well watered. Newly planted rhizomes need moisture for their root systems to develop. Once established, irises should be watered when the top three inches of soil dry out. Over-watering irises is a common mistake once and will lead to rot.

11.     Fertilize with superphosphate or a well-balanced fertilizer with an N-P-K ration of 10-10-10. Avoid fertilizers high in nitrogen as they encourage soft growth that is susceptible to disease.

Bearded iris are a great addition to the garden with their beautiful flowers in spring, and their bold, vertical foliage throughout the growing season. Dividing your plants regularly will keep them vigorous and healthy and provide you with years of enjoyment!

Invasive Vine “Swallows Up” Your Garden

I came home from a week’s vacation to find that my garden had virtually “exploded” while I was gone. The heavy rains of June followed by the July heat wave turned my garden into a lush jungle of towering lilies, heliopsis, and hydrangeas. The explosion of flowers was coupled with an explosion of weeds, including the invasive black swallow-wort vine that I battle every year.

Also known as Louis’ swallow-wort, Cynanchum nigrum is a member of the milkweed family imported to the U.S. from its native Europe as an ornamental vine. It was first noted in Ipswich, MA in 1864, “escaping from the botanic garden where it is a weed and promising to become naturalized.” Since then, black swallow-wort has become an invasive nuisance in the Northeast and Midwest, crowding out native plants in fields and forests. It is also a deadly host for the monarch butterfly, which lays its eggs on the vine, but its larvae do not survive feeding on this plant. Conservancy groups throughout the country are trying to educate the public about the threat of this plant to the environment.

The vines emerge in the spring, and can literally grow a foot overnight in wet weather. They quickly wind around your precious peonies, pulling the heavy blooms down to the ground, sprawl over entire shrubs, or grow right through the center of a rare epimedium that you bought from a hybridizer for a tidy sum. These vines thrive everywhere, from sun or shade, rich humus or heavy clay, alkaline or acidic soil.

Black swallow-wort sports glossy oval-shaped leaves with pointed tips, 3-4 inches long, that occur in pairs along the stem.

The small, dark purple flowers are star-shaped and borne in clusters.

The flowers are self-pollinating and quickly produce a bounty of seed pods that dangle from the stems. The seeds are equipped with their own downy parachutes that aid in wind dispersal, which begins in late July and continues through fall. The plants also spread through underground rhizomes that form large clumps.

So how do we control this thug in the garden? As with all invasive species, early detection and removal is the best approach. There are no biological controls for black swallow-wort available in the U.S. Mowing will not eradicate the plants, but will at least prevent them from forming seeds. Once seeds have formed, the plants should be carefully cut down and bagged so that the seeds don’t disperse. The vines can also be dug out, but care must be taken to remove the complete root crown, which is difficult to do. Even a tiny piece of white root left behind will soon sprout into a new plant. Dug plants should be burned or bagged and disposed of in the trash.

Although I dislike using herbicides in the garden, chemical control is recommended as the most effective means for large, established infestations. Glyphosate (Roundup) is effective if sprayed on when the plants are in flower (prior to that, the plants do not have enough leaf surface area to deliver a killing dose to the roots.) If the black swallow-wort is twining around desirable plants, the glyphosate can be applied with a sponge or brush. Another alternative to spraying is to cut and dispose of the stems and apply a 100% solution of the herbicide concentrate directly to the cut stem surfaces with a small brush.

Unfortunately, once black swallow-wort appears in your garden, you will be battling it for several years. So don’t wait – if you see even the tiniest sprout of this tenacious vine, pull it immediately! Or you may return from vacation later this summer to find your favorite plants “swallowed up” by this insidious creeper!

Vigorous and Carefree Climber: Clematis Viticella

Given that there are over 300 species of clematis and several thousand hybrids, it is no wonder it can be difficult to choose the right ones for your garden. If, like me, you prefer plants that are fuss free and easy to care for and bloom over a long season, then look no further than the vines in the clematis viticella group.

Clematis 'Betty Corning'

The  Viticellas  all share certain attributes that make them outstanding garden plants; they are highly tolerant of both sun and shade, they are disease resistant ( never succumbing to the dreaded clematis wilt), they  bloom profusely for many weeks in the summer, and are all extremely winter hardy ( most to zone 4 ,some to zone 3).

Clematis 'Albu Luxurians'

Many viticellas, like the pale lilac ‘Betty Corning’ sport delicate nodding bell- shaped flowers. This beautiful vine grows 10-12 feet very quickly and can easily bloom 16-18 weeks non-stop. Some other great viticella cultivars are ‘Alba Luxurians’ with its green tipped white flowers and dark purple stamens that put on quite a show , the vibrant red ‘Madame Julia Correvon’ , the aptly named  ‘Abundance’ that is continuously  smothered in reddish- pink semi nodding blooms , and the funky double flowered ‘Purpurea plena elegans’ .

Clematis "Purpurea Plena Elegans"

The viticella group are all perfectly suited to growing through large shrubs and small trees including viburnums, lilacs, hollies and forsythias and crab apples, giving these spring bloomers another season of interest when the clematis flowers hang down from their branches. Here in my garden I grow ‘Kermesina’ through my willows, and the dark dramatic purple ’Etoille Violette’  (an RHS Award winner) through my holly bushes,  and ‘Betty Corning through more shrubs than I can count!

 They are equally at home on a large trellis or fence where they will brighten any corner of your garden with their carefree blooms. All clematis in this group get hard pruned, meaning you cut them back to 8-12 inches from the ground in late winter/early spring.

Like all clematis they will benefit from deep planting, placing the crown of the plant 2-3 inches below the soil line and close attention to watering in the first year after planting to ensure their root system gets well established.  Once these gorgeous vines get going their profusion of bloom will be matched only by the profusion of compliments you will receive from your garden visitors. Feel free to take them all in and never ever tell how very easy this stunning vine is to grow.

Wakefield Estate Featured in Open Days Program

In the effort to increase public knowledge about the importance of historic landscapes, hundreds of exceptional gardens nationwide are selected to participate in The Garden Conservancy’s Open Days program. This year, the Mary M. B. Wakefield Charitable Trust has partnered with the Conservancy to organize “the Greater Boston Area Open Days” on Saturday, June 8, from 10:00am – 4:00pm. Five distinct Milton gardens will be showcased, offering visitors a diverse range of designed landscapes. 

The Wakefield Estate is the former home of Mary “Polly” Wakefield (1914-2004), a trained horticulturist, landscape designer, plant propagator and collector, and an advocate and leader on many environmental issues of her day. Her vision for the purpose of the Wakefield Estate was to “organize to re-establish the contact between the land and the people.” An active member and trustee of many garden and volunteer organizations, Polly was especially passionate about the revival of the Public Garden in Boston. As a founding member of the Friends of the Public Garden, Polly was instrumental in restoring one of Boston’s most beautiful landmarks to its original glory.

One of the strong themes in Polly’s life was her avid interest in science and nature, both observing and studying it. Polly continually augmented her knowledge, accumulating a broad understanding of arboriculture and propagation methods, ultimately leading to her development, selection and naming of eight patented dogwood cultivars, including “Greensleeves” and “Fanfare”, two of the most highly praised dogwood cultivars today. She strived to create a formal garden that defied formality and convention, tested nature’s limits and embraced whimsy and a bit of the wild. An innovator when it came to sustainable gardening methods, she deliberately “crowded” her plants, remarking that “nature prefers it this way,” adding that “it eliminates much weeding … while giving it a more natural appearance and retaining a more even degree of natural moisture.”

The Open Days program coincides with the kick-off of the Wakefield Estate’s annual “Dogwood Days” – a week-long celebration of the estate’s hundreds of flowering kousa dogwood trees. Dogwood Days, which runs from June 8–14, 10am – 4pm daily, features tours, open gardens, and a tree and plant sale including kousa dogwoods, Japanese maples, river birches, eastern red buds, paper bark maples, metasequoias, and larches. New this year is “Dogs and Dogwoods,” a day to bring your canine friend to the estate for dog-friendly events, including a fun and informal dog show.  “Dogs and Dogwoods” is scheduled for Sunday, June 9th, from 10am-4pm.  The dog show will start at 1:00pm.  Dogs must be leashed. 

The Wakefield Estate in located at 1465 Brush Hill Road in Milton. For more information visit www.wakefieldtrust.org or call 617-333-0924. To see a list of the Open Days selected gardens and directions, see The Garden Conservancy’s website: www.gardenconservancy.org.

Davidia Tree – Worth the Wait?

When I first read about Davidia trees, I was immediately fascinated. Imagine finding something that satisfied both my love of flowering trees and my love of unusual plants! It seemed the perfect choice for the long shade border I was creating across my backyard.

So, when I found a Davidia involucrata at an end-of-season sale at Weston Nurseries, I immediately bought it. It was small, only about five feet tall, but I had high hopes. I planted it, nurtured it and awaited the grand show.

After five years had passed with not a flower in sight, I did some homework. I found that not only was it border-line hardy in my area, but it typically did not bloom for twelve years after planting. It was a good grower and created nice shade; its leaves were attractive and it had lovely bark; I consoled myself as I waited for Year Twelve.

Year Twelve came and went. Finally, after thirteen years, I was thrilled when one branch produced some of the most intriguing flowers I had ever seen: fuzzy brown spheres with two white bracts, the larger one nearly seven inches long! This continued for the next couple of years: a branch here and there with a smattering of flowers. But this year, nearly the entire tree is blooming. As the white bracts of each flower flutter in the breeze, I can see why its common names are Handkerchief Tree and Dove-tree. It is just as fascinating as I had imagined.

And, yes, it was worth the wait.

Inspiring Containers from Chanticleer

I was astounded by the beauty of the container plantings at Chanticleer Garden in Wayne, Penn.  Although it was only mid-April, there were dozens of richly planted pots throughout the garden. The containers themselves ranged from formal urns to terracotta, glazed ceramics and modern metals. Many were grouped or strategically placed to enhance the garden's design. I hope that you will be inspired to create your own artistic contained gardens!

The Spring Glory of Chanticleer

To my family's chagrin, I always manage to find a nursery or public garden wherever our travels take us. So last week, when my daughter's college visit took us to the suburbs of Philadelphia, I was delighted to find that we were in the vicinity of the famous Chanticleer garden in Wayne, PA.

Chanticleer has been called the most romantic, imaginative and exciting public garden in America, and seeing it in its spring glory, I heartily agree with this description. The estate, with its 1913 mansion and themed gardens was once the country retreat of the Rosengarten family, whose Philadelphia-based pharmaceutical firm became part of Merck. The landscape was originally designed by Thomas Sears, and the 35 acres that are open to the public are now maintained by a staff of 12 gardeners and groundskeepers.

The terraces surrounding the main house are formally planted with thousands of spring-flowering bulbs.

The Teacup Garden's formal parterre gardens were a colorful tapestry of vegetables, herbs and flowers.

Dozens of lushly planted containers adorned the gardens around the home.

The estate's impressive lawns and trees were blooming with hundreds of daffodils. The saucer magnolias and cherries were magnificent.

The shady gardens of Bell's Woodland were massed with epimediums, ferns, hellebores, trilliums and spring bulbs.

The Gravel Gardens were ablaze with tiny species tulips, miniature daffodils and grape hyacinths.

Naturalized frittilarias adorned a remote, quiet part of the garden.

Chanticleer is open to the public from April through October, and more information can be obtained at www.chanticleergarden.org. It is well worth a visit, and I cannot wait to return someday!

Pulmonaria Pops in the Shade

As a garden designer, one of the questions that I’m often asked is “What can I plant in the shade that the deer won’t eat?” We all know that while hostas may be gorgeous and highly collectible, they are also a tantalizing “salad bar” for grazing deer. Pulmonarias, with their eye-catching foliage and early flowers, are the answer.

Relegated to grandma’s shade garden for many years, Pulmonarias have seen a recent resurgence of popularity as hybridizers have produced wonderful new varieties. Like several other perennials, Pulmonarias are plagued with an unattractive common name – Lungwort, due to the resemblance of their leaves to a diseased lung. But their subtle beauty, hardiness (Zones 3-8), pest and disease resistance make them a great addition to the modern shade garden.

Pulmonaria 'Silver Bouquet'

Pulmonarias are low-growing, clump forming relatives of borage, with similar fuzzy leaves and deep-blue flowers. Like hostas, pulmonarias can be collected just for their foliage contribution to the garden. Leaves range from apple-green to olive and deep emerald, and many are spotted in white or streaked with silver. They also differ in shape, from spear-like to oval. The plants range in size from 8-28” high and 12-24” wide. Outstanding cultivars for foliage include ‘Silver Bouquet’ with solid silver leaves, and ‘Milky Way’ with large white spots.

Pulmonaria 'Milky Way'

In addition to showy foliage, pulmonarias rival hellebores to be the first flowering perennials in the early spring garden. Clusters of funnel-shaped flowers appear in early spring, and many change colors as they age. My pulmonaria flowers transform from sky blue to lavender and pink, and since they open gradually, you see all three colors on the same plant at once!

While pulmonarias are generally known for their deep blue flowers, there are varieties that bloom in white (‘Opal’), salmon (‘Redstart’) and raspberry (‘Berries and Cream’).

Pulmonaria 'Opal'

Pulmonarias are easy to grow in average, humus-rich garden soil, in part to full shade. Moist soils and good drainage ensure the best success. They spread slowly by creeping roots and can be easily divided in late spring or fall. They also cross-pollinate and self-seed naturally, so you may find unexpected new varieties sprouting up in your garden.

Pulmonaria 'Redstart'

Eye-catching as specimen plants, pulmonarias are also effective when massed as a ground cover. They can be artistically combined with almost any shade plants, particularly Japanese Painted Ferns, Coral Bells, Hostas, and Black Mondo grass. No matter how you use them, these old-fashioned, deer-resistant perennials will breathe new life into your shade garden.

Texture Enriches the Winter Garden

When you are designing your garden for winter interest, think of yourself as a set designer. Unlike spring and summer, when the garden goes through many scene changes, the winter stage does not change rapidly. The overall composition is a static one, but it will not be boring if you incorporate the basic principles of design: form, line, color, repetition and texture.

Texture is a sensory perception of our environment, much more subliminal than color or form. During the winter, the garden loses much of its bright color and leafy abundance, so the texture of winter plants becomes much more apparent. When skies are clear, the bright, glittering winter light accentuates the textures in the landscape. Because the angle of the winter sun is low, it reflects light on the glossy foliage of large-leaved evergreens like hollies and laurels, and the shining bark of ornamental trees.

Whether peeling, patchy, shiny or dull, bark is an asset. Botanists have classified bark into 18 different types, including scaly, peeling, flaking, fissured, corky, cracked, and spiny, to name a few. Trees with outstanding peeling bark include the Paperbark maple, River birch, Paper birch, and Shagbark hickory.

Sargent cherry (below) is a stunner with its glossy, burgundy striped bark. Other trees with shiny, colorful bark include Japanese maples and the Prairiefire crabapple.

Stewartias (below) and Kousa dogwoods display patchy bark in camouflage colors. These ornamental trees look best sited against a backdrop of evergreens, which will help to show off their interesting bark.

Evergreen trees and shrubs provide textures with their leaves and needles, and planting evergreens with contrasting textures creates interesting compositions. The large smooth leaves of a rhododendron can be set off with the ferny foliage of Siberian cypress and the fine texture of a boxwood. The soft long needles of an Austrian pine look great next to the shiny, spiky leaves of a blue holly.

Evergreen groundcovers add texture at ground level and perk up the garden when the lawn has turned to a depressing brown. Excellent groundcovers for winter interest include broadleaf evergreens such as pachysandra, vinca, euonymous, or gaultheria, and low-growing conifers such as ‘Nana’ or ‘Blue Star’ junipers.

Although many gardeners like to deadhead spent flowers in the fall, dried blooms and seedheads of sedums, astilbes, black-eyed susans and ornamental grasses enrich the winter landscape. The dried flowers of hydrangeas, pieris and leucothoe also add a nice texture to the garden, and look particularly beautiful when dusted with snow.

Berries, fruits and hips are like exclamation points in the landscape. The fruits of a hawthorn tree, the berries of cotoneasters, hollies and junipers, or the hips of a climbing rose add a delightful texture, especially when covered with frost.

Texture in the garden is most visible and effective when seen in contrast: lustrous with dull, prickly with smooth, ribbed with flat, feathery with broad, needled with flat. As the “set designer” of your garden, you can create a beautiful winter scene with the endless variety of textures exhibited by our trees, shrubs and herbaceous plants.

The Blazing Beauty of 'Midwinter Fire'

I have always admired bloodtwig dogwood (Cornus sanguinea) for its colorful contribution to the winter garden. During a recent visit to Tower Hill, I fell in love with a new cultivar of this wonderful plant – ‘Midwinter Fire’. This outstanding ornamental shrub features stems that are yellow at the base, igniting to shades of coral and culminating to fiery orange-red at the tips. Planted as a formal hedge with small boxwood at its feet in the new winter garden courtyard at Tower Hill, it was absolutely stunning.

This shrub is a plant for all seasons, with oval medium-green leaves, clusters of tiny white flowers in late spring, dark purple berries in summer, and golden autumn foliage. It grows to 5’ tall and 6’ wide, and looks great backed by dark green shrubs. For more information about growing and caring for bloodtwig dogwoods, please see our previous blog article.

‘Midwinter Fire’ makes a spectacular container plant surrounded by snowdrops and black mondo grass.

Dazzling Hellebores for 2013

Hellebores have fascinated me ever since I saw huge swaths of them blooming in a Washington, DC botanic garden 12 years ago. I started with a few plants in one garden bed, and as they faithfully returned year after year, I added more varieties, began dividing my own plants, and growing on seedlings in nursery beds. At this time of year, though, I realize that I just don't have enough of these amazing winter bloomers.

As I scouted the websites for new plants, I thought that I would share with you some of the dazzling varieties available to gardeners in 2013.
